* avformat/utils: Stream specifier enhancement 2.Bela Bodecs2018-04-131-2/+8
| | | | | | | | | | | | | | | | | In some cases, mainly working with multiprogram mpeg-ts containers as input, it would be handy to select sub stream of a specific program by their metadata. This patch makes it possible to narrow the stream selection among streams of the specified program by stream metadata. Examples: p:601:m:language:hun will select all sub streams of program with id 601 where sub streams have metadata key named 'language' with value 'hun'. p:602:m:guide will select all sub streams of program with id 602 where sub streams have metadata key named 'guide'.

* avformat/utils: Stream specifier enhancementBela Bodecs2018-04-121-3/+7
| | | | | | | | | | | | | | | | | | | | Currently when specifying the program id you can only decide to select all stream of the specified program (e.g. p:103 will select all streams of program 103) or narrow the selection to a specific stream sub index (e.g. p:145:1 will select 2nd stream of program 145.) But you can not specify like all audio streams of program 145 or 3rd video stream of program 311. In some case, mainly working with multiprogram mpeg-ts containers as input, this feature would be handy. This patch makes it possible to narrow the stream selection among streams of the specified program by stream type and optionally its index. Handled types: a, v, s, d. Examples: p:601:a will select all audio streams of program 601, p:603:a:1 will select 2nd audio streams of program 603, p:604:v:0 will select first video stream of program 604.

* avutil/pixdesc: deprecate AV_PIX_FMT_FLAG_PSEUDOPALwm42018-04-031-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | PSEUDOPAL pixel formats are not paletted, but carried a palette with the intention of allowing code to treat unpaletted formats as paletted. The palette simply mapped the byte values to the resulting RGB values, making it some sort of LUT for RGB conversion. It was used for 1 byte formats only: RGB4_BYTE, BGR4_BYTE, RGB8, BGR8, GRAY8. The first 4 are awfully obscure, used only by some ancient bitmap formats. The last one, GRAY8, is more common, but its treatment is grossly incorrect. It considers full range GRAY8 only, so GRAY8 coming from typical Y video planes was not mapped to the correct RGB values. This cannot be fixed, because AVFrame.color_range can be freely changed at runtime, and there is nothing to ensure the pseudo palette is updated. Also, nothing actually used the PSEUDOPAL palette data, except xwdenc (trivially changed in the previous commit). All other code had to treat it as a special case, just to ignore or to propagate palette data. In conclusion, this was just a very strange old mechnaism that has no real justification to exist anymore (although it may have been nice and useful in the past). Now it's an artifact that makes the API harder to use: API users who allocate their own pixel data have to be aware that they need to allocate the palette, or FFmpeg will crash on them in _some_ situations. On top of this, there was no API to allocate the pseuo palette outside of av_frame_get_buffer(). This patch not only deprecates AV_PIX_FMT_FLAG_PSEUDOPAL, but also makes the pseudo palette optional. Nothing accesses it anymore, though if it's set, it's propagated. It's still allocated and initialized for compatibility with API users that rely on this feature. But new API users do not need to allocate it. This was an explicit goal of this patch. Most changes replace AV_PIX_FMT_FLAG_PSEUDOPAL with FF_PSEUDOPAL. I first tried #ifdefing all code, but it was a mess. The FF_PSEUDOPAL macro reduces the mess, and still allows defining FF_API_PSEUDOPAL to 0. Passes FATE with FF_API_PSEUDOPAL enabled and disabled. In addition, FATE passes with FF_API_PSEUDOPAL set to 1, but with allocation functions manually changed to not allocating a palette.
